Abstract

System for overvåkningsoperasjoner under vann System for undersjøiske overvåkningsoperasjoner, f.eks. av sjøbunnen, iskartlegging eller oppsporing av rørledning, omfattende et autonomt, ubemannet undersjøisk fartøy med fremdrifts- og styreorganer (4-8, 10, 11), et navigasjonssystem (38) omfattende bevegelsesavfølende og posisjonerende organer samt et adaptivt autopilotsystem (41) for fremdrift av fartøyet via en forhåndsbestemt undersjøisk bane. Et syntetisk apertursonarsystem (42) omfatter en sonar- transmisjons- og mottakergruppe (43) av en lengde som definerer en begrenset fysisk apertur anordnet på en overflatedel (32) av fartøyet for å observere ekkosignaler som reaksjon på utsendingen av sonar- signaler gjennom en del av nevnte bane som definerer en syntetisk apertur av en lengde som er mange gang- er større enn nevnte fysiske apertur, Autopilotsys- temet (41) blir styrt for å registrere eventuelt avvik ved fremdriften av fartøyet i forhold til nevnte bane og å frembringe en tilsvarende korrigert beskrivelse av den forhåndsbestemte bane innenfor en margin som utgjør en brøkdel av bølgelengden for sonarsignalene. Sett av ekkosignalverdier som blir innsamlet innenfor nevnte syntetiske apertur, blir lagret i lagringsorganer (44) og det er anordnet signalprosesseringsorganer (54-57) for å prosessere nevnte lagrede sett og for å generere høyoppløselige billedinformasjonsdata svarende dertil.System for underwater monitoring operations System for underwater monitoring operations, e.g. of the seabed, ice mapping or pipeline tracking, comprising an autonomous, unmanned undersea vessel with propulsion and steering means (4-8, 10, 11), a navigation system (38) comprising motion sensing and positioning means, and an adaptive autopilot system (41) for propulsion of the vessel via a predetermined submarine trajectory. A synthetic aperture sonar system (42) comprises a sonar transmission and receiver group (43) of a length defining a restricted physical aperture disposed on a surface portion (32) of the vessel to observe echo signals in response to the transmission of sonar signals through a portion. of said trajectory defining a synthetic aperture of a length many times greater than said physical aperture, the Autopilot system (41) is controlled to detect any deviation in the progress of the vessel relative to said trajectory and to produce a corresponding corrected description of the predetermined path within a margin constituting a fraction of the wavelength of the sonar signals. Sets of echo signal values collected within said synthetic aperture are stored in storage means (44) and signal processing means (54-57) are arranged to process said stored sets and to generate high resolution image information data corresponding thereto.
